The Black Book of Poland is so named because of the black record of German barbarism from the close of the war in Poland, which ended October 6, 1939, until the end of June, 1941, thus covering twenty-two months, as shown in documents contained in this volume. No comment is offered. The facts are unmitigated and have been classified according to topics, to facilitate reference. This represents the most astounding collection of documents ever presented both in text and photographic reproduction. Long after the war is over, this testimonial of unspeakable barbarity will stand as a monument of accusation.
